Title: Polishing energy control device
Inventor: SHIMADA AKIRA
IPC: B23Q15/12
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a polishing energy control device that can provide a high quality polished face by controlling friction force, which is required for polishing a workpiece, so that polishing energy becomes a given specified value. SOLUTION: Friction force is generated between a workpiece 7 and the portion which a polishing device 1 contacts. The component F (t) of this friction force in the tangential direction is compared with a force command value to determine the error between the two. The force that a robot 9 put to press the workpiece 7 against the polishing device 1 is controlled based on the error. Since the integral of friction force and polishing speed with the lapse of time corresponds to friction energy, the control between the friction force and polishing time accords with the control of polishing energy. The direct control of friction force makes it possible to provide high quality and stable polished faces without being affected by the change in the coefficient of friction.
